STUDY OBJECTIVES: To assess whether poor sleep quality experienced by regular shift workers and individuals with obstructive sleep apnea (OSA) affects neurobehavioral function similarly, or whether the different aetiologies have distinct patterns of impairment.
METHODS: 37 shift workers (> 24 hours after their last shift), 36 untreated patients with OSA and 39 healthy controls underwent assessment of sleepiness (Epworth Sleepiness Scale [ESS], Oxford Sleep Resistance Test), mood (Beck Depression Index, State Trait Anxiety Inventory [STAI], Profile of Mood States), vigilance (Psychomotor Vigilance Task [PVT], AusEd driving simulation), neurocognitive function (Logical Memory, Trails Making Task, Digit Span and Victoria Stroop Test) and polysomnography.
RESULTS: There were no significant differences between the groups in respect to sleepiness (ESS score [median, IQR] = 10.5, 6.3-14 versus 7, 5-11.5 for OSA group and shift work group, respectively) or mood, with the exception of state anxiety which was elevated in the OSA group (STAI score [median, IQR] = 35, 29-43 versus 30, 24-33.5 for OSA group and shift work group, respectively). However, the OSA group performed significantly worse than the shift work group on the driving task (crash proportion = 46.9% versus 18.9% for OSA group and shift work group, respectively) and the PVT (lapses [median, IQR] = 3, 2-6 versus 2, 0-3.5 for OSA group and shift work group, respectively), as well as most of the neurocognitive measures.
CONCLUSIONS: Participants with OSA had similar sleepiness and mood to the shift work group, but worse vigilance and neurocognitive function. These findings suggest that distinct causes of sleep disturbance likely result in different patterns of neurobehavioral dysfunction.
